Aimpoint Comp M2 for LEOs

[SW CQB 45]

I took delivery of 25 very used Comp M2 to be used on Patrol Rifles. The SWAT commander for our dept got these on some govt program.

I am getting mixed information and the Aimpoint Instruction manual somewhat differs from what was told to me.

I would like to ask those who have time behind the older M2 as I have to instruct LEOs on how to use them.

It mainly has to do with battery life and whether to leave them on or not.

Cosmetically, these optics are beat up but every one works and they have low mounts that will co-witness with the back up irons.

I was told by some LEOs who were overseas that the battery life on the M68 or Comp M2 was about 40 hours if left on.

I was also told that the Comp M2 circuitry will power down on its own if left on.

I recently downloaded the Aimpoint manual from the internet and it says 1000 hrs for battery life.

I could not find anything in the manual related to auto shut off.

The batteries are the CR-1/3N.

what is odd is some came with 2 batteries in order to power on and some have some sort of thin metal spacer and only require 1 battery to work.

Is the spacer just taking up space or is it a place for the spare battery and if the Comp M2 only requires 1 battery, is it overloading the system with 2 batteries?

I was told Aimpoint will not honor any warranty/issues on the program Optics lent to depts so I am reluctant to call them.

one more thing to add….to add even more head scratching…a lot of the battery covers are different….some are short, long, some hold two batteries side by side and one will hold one battery with another battery on the outside/outside cover and some had the inner metal housing.

thanks in advance

I was under the impression the battery life for the older model was 10,000 hours, and a lot higher for the newer versions, better circuitry .

Yes there is a double battery holder, that spacer holds the spare battery away from the main battery being used. I have a cap for my but no spacer.

As far I know it does not shut off automatically , and there is no off position anyways , the lowest setting is the lowest NV setting.

I have an old M2. Will agree that I believe the battery life is about 10K hours. Am on my second of third battery, can't recall, but remember with the first one I turned the site on after having used it for a number of years only being on at the range, and it lasted for a few months before at setting of 5 or 6 it died and I replaced. Will note that it will dim once the battery begins to die so if you are cranking it to the max and think it is still dim that it is a good idea to change it.

All in all, they are decent sites, though I think the newer models are better, what with 2MOA dots and better battery life, but they are certainly usable and mine is still rocking.

thanks for the info.

does yours just use one battery and has the other battery in a metal sleeve?

[jonconsiglio]

I'm insulted that I have not received a text about this Mike!

I'd suggest your guys leave them on and change batteries on a set schedule. Battery life is dependent on the setting. Let's say a T1 has a battery life of six years. That's on setting 8 of 12. If left on setting 12, it's more like two years.

10,000 hours is about a year, a little more. I'd say leave them on constantly for the setting preferred by the officer, and chance the batteries quarterly.

I am just using the single battery. Have looked at the spare battery holder, but am running it in a LT129 mount and it has a spare compartment on the mount that I keep a spare battery in.

Jon.....I thought these "guys" (M2s) would be dinosaurs to a high roller like you. Hahaha!

I will contact you later.

My son is on a dinosaur kick right now, what can I say!

Oh, that 1,000 hours is going to be when left on setting 10, your extra bright setting. That setting is for direct sunlight, and even then it can be too bright. More like for use in snow and bright sun, when wearing sunglasses, etc.

It would probably be best for a day shift officer to leave it on something like setting 9 and maybe setting 8 when working night shift, depending on the light mounted. With the lights you guys are running, setting 8 should be pretty good. Not too much bloom in darkness and not washed out when the light is activated.

Of course, each officer will have their own preference.

The few lucky ones in our agency who have Aimpoints are told to change the batteries every 6 months when they change the batteries at home in their smoke detectors. It's just a helpful way for them to remember and it plays it safe even though they can go much longer.

I have a ML2 that I purchased 16 years ago and it is on it's third battery. I thought that the primary difference between the M2 and ML2 was that the ML2 was not night vision compatible.

A shooting buddy showed up at a Run 'n Gun match and pulled his carbine out of the case. He noticed that he forgot to turn off his ML2 after a match he shot 6 months earlier. The ML2 was still working.

Battery life is suppose to be quite good.
